[0041] Reference Figures 1 to 6 The hidden massage device includes a massage movement 1, a flip frame 2 and an electro-driven drive rod. The electro-driven drive rod has an electric push rod 3 or a gear rack combination. The former is a commercially available product and is the preferred option, the same below. An axial hole 21 is provided at one end of the flip frame 2, which can be swingably hinged to the upper crossbeam of the fixed frame by means of the axial hole 21. An axial ear 22 is provided in the middle of the bottom surface of the flip frame. One end of the electric push rod 3 is hinged to the axial ear 22 and the other end is hinged to the lower crossbeam of the fixed frame. The electric push rod 3 controls the flip frame 2 to rise to the designed working surface of the massage movement and fold and hide, that is, to rise for massage and lower for storage. The two axial holes 21 of the flip frame 2 are suspended on the upper crossbeam and supported by the electric push rod 3 in the middle, forming a three-point stable support that can withstand the weight of the human body.

[0042] like Figure 1 and Figure 2 The massage movement 1 is a rotary massage movement and / or a shaking massage movement. The rotary massage movement is a common module, including a motor 11, a transmission chain 12 and a massage head 13. The motor 11 is decelerated by the transmission chain 12 and generates multiple output shafts. Each output shaft drives a massage head 13. The motor drives multiple massage heads to rotate and / or beat, and the combination forms a kneading massage technique, such as Figure 1 and Figure 2What is demonstrated is exactly the combination of rotary massage head and beating massage head. What should be explained here is that, the inherent eccentric shaft section 14 is locked on the outgoing shaft of driving beating massage head, and the ups and downs that the eccentric shaft section 14 produces are utilized to make massage head 13 produce beating phenomenon in one direction.

[0043] The vibration massage movement is also driven by the motor 11, and there are two specific forms:

[0044] 1. As Figure 3 and Figure 4 The reciprocating shaking mechanism includes a motor 11, a transmission chain 12, a connecting rod 15, and a shaking plate 16. The shaking plate 16 is positioned on the flip frame 2 by several elastic columns, which are rubber columns 17 or springs, one end of which is locked to the shaking plate 16 and the other end is locked to the flip plate 2. In this embodiment, rubber columns 17 are preferred. With the help of rubber columns 17 or springs, the shaking plate 16 can be supported and properly offset to generate shaking under the drive of the motor.

[0045] The motor 11 and the transmission chain 12 are fixed on the turning frame 2. The transmission chain 12 is provided with an eccentric shaft section 14 at the shaft end. One end of the connecting rod 15 is sleeved on the eccentric shaft section 14 and the other end is hinged to the bottom surface of the shaking plate 16, pulling the shaking plate 16 to reciprocate. Figure 3 and Figure 4 The traction reciprocating motion can be designed to be perpendicular to or parallel to the swing hinge direction of the turnover frame 2, depending on specific needs. This shaking solution can produce clear front-back or left-right shaking.

[0046] 2. If Figure 5 and Figure 6 , rotary shaking, including a motor 11 and a shaking plate 16; the shaking plate 16 is positioned on the flip frame 2 through several rubber columns 17, and the motor 11 is fixed on the flip frame 2. The output shaft end of the motor 11 or the output shaft end through the transmission chain is provided with an eccentric shaft segment 14, and the eccentric shaft segment 14 can be rotatably inserted into the shaft sleeve 161 on the bottom surface of the shaking plate 16 to drive the shaking plate 16 to swing, that is, the shaking plate can do 360-degree shaking and swinging; a bearing 18 or a self-lubricating copper sleeve is provided between the shaft sleeve 161 and the eccentric shaft segment 14 to reduce wear and noise. The transmission chain 12 is not added in the legend, because the direct drive speed of the motor 11 is faster, producing a similar vibration effect, and the transmission chain 12 is added to slow down. At this time, the eccentricity of the eccentric shaft segment 14 can be increased to produce a larger amplitude of slow swing. The above Figures 3 to 6 Electric push rods are omitted.

[0047] The above is the structure of the hidden massage device, which can be matched with various types of seats to realize the massage function without changing the original function of the seat. The details are as follows:

[0048] Reference Figures 7 to 12A massage chair comprises a seat frame 4, a backrest frame 5 and a base frame 6, as well as the above-mentioned hidden massage device; the backrest frame 5 is positioned at the rear end of the seat frame 4, and the seat frame 4 can be swung and positioned on the base frame 6 to achieve continuous change from a sitting position to a lying position, and is also driven by an electric push rod 3, such as Figure 1 One end is hinged to the front end of the seat frame 4, and the other end is hinged to the base frame 6. The base frame 6 is used to provide stable support on the ground. The electric push rod 3 used to drive the seat frame 4 to swing is generally located in the middle to balance the weight on both sides. To this end, a bottom beam 61 is provided at the bottom of the base frame 6, connecting the two sides and providing a point of force for the electric push rod. The complete massage chair also includes a leg frame suspended from the front end of the seat frame 4, which can adjust to the changes in sitting and lying. Since it is not related to the content of this application and has no structural connection, it is omitted in the figure.

[0049] The seat frame 4 is hinged with a tilting frame 2 on at least the upper crossbeam 41 at the front end. The lower end of the electric push rod 3 that drives the tilting frame 2 is hinged on the lower crossbeam 42 at the front end of the seat frame. The electric push rod 3 drives the tilting frame 2 to rise and fall. When the tilting frame is raised, the massage mechanism 1 supported by the massage mechanism 1 has an operating surface at the same height as the seat cushion, which means that it can contact the human buttocks and achieve an effective massage. There are also two typical structures of massage chairs, as follows:

[0050] 1. The seat frame 4 and backrest frame 5 are connected as one piece, with an L-shaped track 51 between them for the running mechanism to run continuously. Since the running mechanism is not involved, it is omitted in the figure. A rectangular frame consisting of an upper crossbeam 41 and a lower crossbeam 42 is set at the front end of the seat frame 4. In the sitting position, this rectangular frame is located in front of the bottom frame 6, more specifically, at the front end of the bottom beams 61 on both sides, so as not to affect the movement space of the electric push rod. In order to strengthen the force stability of the rectangular frame at the front end of the seat frame 4, without affecting the spatial relationship, it can be connected to the rear beam through the longitudinal rods 43 on both sides to form a rectangular body to improve the rigidity and vibration resistance. Figure 12 .

[0051] The flip frame 2 hinged on the upper crossbeam 41 can be raised to enter the space between the two L-shaped tracks 51, and the flip frame 2 is equipped with a shaking massage movement, that is, when it is raised, the shaking plate 16 can come into contact with the buttocks and transmit the shaking to the human body; and the kneading massage is completed by the original walking movement.

[0052] The flip frame 2 descends and the shaking plate 16 is folded to the front end of the cushion frame 4, which does not affect the full walking space of the walking movement on the L-shaped track 51, retaining the massage function of the original walking massage chair. When the control program sets the walking movement to move back and forth on the backrest frame 5, the electric push rod 3 can be started to raise the flip frame 2, and the shaking plate 16 can be used to generate shaking massage. It can work independently or synchronously to enrich the massage experience.

[0053] 2. Reference Figure 13 and Figure 14 The seat frame 4 and backrest frame 5 are separate components. The seat frame is a rectangular body, with both front and rear ends containing a rectangular frame consisting of an upper crossbeam 41 and a lower crossbeam 42. These are connected by longitudinal beams 43 on either side. A flip frame 2 is hinged to each upper crossbeam 41 at the front and rear ends. The lower end of the electric push rod 3 that drives the flip frame is hinged to the lower crossbeam 42 at the corresponding end, driving the two flip frames 2 to alternately enter the seat cushion space. One flip frame 2 is equipped with a rotary massage mechanism, while the other is equipped with a vibrating massage mechanism. Switching between these two modes is controlled by a control program, achieving two massage modes and overcoming the drawback of traditional massage methods that only have one method.

[0054] This structure is also applicable to sofa chairs, such as Figure 14 After omitting the base frame 6, it becomes a sofa chair bracket consisting of a ground-mounted seat cushion frame 4 and a backrest frame 5, which is suitable for small sofa chairs and improves the massage experience. It has both shaking and kneading massage functions, thereby improving the use efficiency of the sofa chair. Especially when the rotary massage movement is hidden, the comfort of the chair is greatly improved.
